Lumen-measuring devices and method
View Patent ↗The present invention provides a lumen measuring device and method that allows the user to calculate the exact length and diameter of a suitable interventional prosthesis as well as the height and length of stenosis during the same exploratory procedure.
1. A device that is configured to allow a user to measure a diameter of a body lumen, the device comprising:
a diameter measurement balloon comprising distal and proximal surfaces, the diameter measurement balloon having concentric diameter measurement markers on the proximal and/or distal surface thereof;
a dilation balloon that is configured to radially expand to dilate a stenosis within the body lumen; and
a plurality of conduits, comprising: a diameter measurement conduit for inflating the diameter measurement balloon, and a dilation conduit for inflating the dilation balloon.
2. The device of claim 1 , wherein the plurality of conduits are co-extruded.
3. The device of claim 1 , further comprising an optical scope.
4. A method of measuring a diameter of a target segment of a lumen of a patient, the method comprising:
providing a measuring device, comprising:
a diameter measurement balloon comprising distal and proximal surfaces, the diameter measurement balloon having concentric diameter measurement markers on the proximal and/or distal surface thereof;
a dilation balloon that is configured to radially expand to dilate a stenosis within the body lumen; and
a plurality of conduits, comprising: a diameter measurement conduit for inflating the diameter measurement balloon, and a dilation conduit for inflating the dilation balloon;
introducing the device into an appropriate anatomical orifice of the patient;
delivering the device adjacent the target segment of the lumen within the patient; and
measuring the diameter of the target segment of the lumen within the patient.
5. The method of claim 4 , wherein the measuring device further comprises an optical scope operatively coupled therewith, such that the measuring step is accomplished utilizing the optical scope.
6. The method of claim 4 , wherein the target segment of the lumen is stenotic.
7. The method of claim 4 , further comprising measuring another dimension of the target segment, wherein the dimension is selected from the group consisting of length, height, and circumference.
8. A device that is configured to allow a user to measure a diameter of a body lumen, the device comprising:
a diameter measurement balloon comprising smooth distal and proximal surfaces, the diameter measurement balloon having diameter measurement markers on the proximal and/or distal surface thereof;
a dilation balloon that is configured to radially expand to dilate a stenosis within the body lumen; and
a tube having an interior and an exterior, the interior defining three conduits passing at least partially therethrough, the first conduit comprising a diameter measurement conduit for inflating the diameter measurement balloon, the second conduit comprising a dilation conduit for inflating the dilation balloon and a third conduit that extends the length of the tube.
9. The device of claim 8 , wherein the tube further comprises proximal and distal ends and measurement markings therebetween.
10. The device of claim 8 , further comprising an optical scope.
11. A method of measuring a diameter of a target segment of a lumen of a patient, the method comprising:
providing a measuring device, comprising:
a diameter measurement balloon comprising smooth distal and proximal surfaces, the diameter measurement balloon having diameter measurement markers on the proximal and/or distal surface thereof;
a dilation balloon that is configured to radially expand to dilate a stenosis within the body lumen; and
a tube having an interior and an exterior, the interior defining three conduits passing at least partially therethrough, the first conduit comprising a diameter measurement conduit for inflating the diameter measurement balloon, the second conduit comprising a dilation conduit for inflating the dilation balloon and a third conduit that extends the length of the tube;
introducing the device into an appropriate anatomical orifice of the patient;
delivering the device adjacent the target segment of the lumen within the patient; and
measuring the diameter of the target segment of the lumen within the patient.
12. The method of claim 11 , wherein the measuring device further comprises an optical scope operatively coupled therewith, such that the measuring step is accomplished using utilizing the optical scope.
13. The method of claim 11 , wherein the target segment of the lumen is stenotic.
14. The method of claim 11 , further comprising measuring another dimension of the target segment, wherein the dimension is selected from the group consisting of length, height, and circumference.
